Disclosed is a display control device mounted in a vehicle and including: an irradiation control unit for controlling an irradiating unit that irradiates a road surface with reference light; and a projection control unit for controlling a projecting unit that projects an image onto a reflecting unit that reflects the image, in which the irradiation control unit instructs the irradiating unit to perform irradiation with the reference light, the irradiation corresponding to set irradiation distance information, and the projection control unit instructs the projecting unit to perform projection of an image in such a way that a virtual image corresponding to the irradiation distance information is visually recognized by an occupant of the vehicle, and also controls either a projection position or a projection size of the image projected by the projecting unit on the basis of an instruction of the occupant.

Display control device

A navigation device or method is configured to identify location information and a route setting method from a recognition result obtained by constantly recognizing user's utterance contents, and set a route based on the location information and the route setting method.

Navigation device and method

A vehicle-mounted voice recognition apparatus including a voice input unit for acquiring an inputted voice, a voice recognition unit for performing voice recognition on the acquired inputted voice, a guidance information output unit for providing a guidance on the basis of the result of the voice recognition, and a recognized word understanding degree determining unit for determining a user's degree of understanding of recognized words to the guidance according to the number of timeout times that a timeout has occurred in the user's operation which is monitored while the voice recognition unit performs the voice recognition, and the number of correction times that a correction has been made to the user's operation, so as to change the guidance provided by the guidance information output unit.

Vehicle-mounted voice recognition and guidance apparatus

A voice recognition apparatuscarries out voice recognition of an inputted voice with reference to a voice recognition dictionary, and outputs a voice recognition result. In this voice recognition apparatus, a plurality of voice recognition dictionaries-to-N are provided according to predetermined classification items. The voice recognition apparatus further includes a voice recognition meanswhich carries out voice recognition of the inputted voice with reference to one of the voice recognition dictionaries so as to acquire the above-mentioned voice recognition result, an erroneous recognition judging meanswhich judges whether or not the voice recognition result indicates erroneous recognition, a recognition dictionary management meanswhich switches among the voice recognition dictionaries when the voice recognition means judges that the voice recognition result indicates erroneous recognition, and a voice recognition meanswhich carries out voice recognition of the inputted voice with reference to a switched-to voice recognition dictionary so as to acquire a voice recognition result.
